This is a problem a few customers have encountered. However, there is a newdriver available from Silicon Laboratories that may resolve this issue (youcan download the updated driver from the link below).

The link to the driver has been removed as it is no longer available - please see below

After doing some investigation about the driver link from above, I have found that Davis has come out with a new version of WeatherLink where the new driver is included. The new version of WeatherLink is 5.7.0
